CHARLES D. HOUSE, OF CENTER CITY, TEXAS.

SAW-CLEANER. FOR COTTON-GINS.

Application filed May 3, 1911.

To all whom it may concern:

Be it known that 1, CHARLES D. Home, a citizen of the United States, residing at Center City, in the county of Mills and State of Texas, have invented a new and useful Saw-Cleaner for Cotton-Gins, of which the following is a specification.

This invention relates to saw cleaning attachments for cotton gins, its object being to provide a simple form of device of this character which can be readily applied to a cotton gin and which frictionally engages the two faces of each of the saws so that, when the gang of saws is rotated backwardly, by hand or any other power, any accumulations upon the saws will be scraped therefrom.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings :Figure 1 is a plan view of the attachment in position, a portion of a gang of saws being shown. Fig. 2 is a longitudinal section through the attachment and through the gang of saws, portions of the gin and a saw being shown. Fig. 8 is a section on line 3-3 Fig. 1. Fig. 1 is a perspective view of one of the pairs of scraping lmives.

Referring to the figures by characters of reference 1 designates a connecting strip of wood or other suitable material and secured to one face of this strip is a series of knives arranged in pairs. These knives are of spring metal and the knives of each pair are secured, at one end, to the strip 1, said ends being placed one upon the other, as indicated at 2 and being held by screws 3 or the like. The knives are then given a one-quarter twist, as shown at 4:, and are extended with their faces diverging upwardly but with their upper or scraping edges parallel,

as shown at 5. The free ends of the knives are then brought together in substantially parallel relation, as shown at 6 and are riveted or otherwise secured to opposite faces of the flattened end 7 of a curved finger 8. The various knives of the series are so proportioned and located that, when they are all attached to the strip 1, the knives of each pair converge upwardly toward the knives of the next adjoining pairs so that they are spaced apart along their scraping edges a distance slightly less than the thickness of the saws to be cleaned.

In using the attachment, the strip 1 is placed upon a supporting ledge A within the gin while the curved fingers 8 are inserted between the saws B and upon the spacing rings C. The saws will therefore extend between the various pairs of blades and these blades converge upwardly toward the saws and with their straight scraping edges in contact therewith, the lower faces of the blades being located at acute angles to the faces of the saws. After the attachment has thus been placed in position, the saws are rotated backwardly and as the scraping edges of the blades extend from the peripheries of the saws to points adjacent the centers thereof, it will be obvious that, during this rotation of the saws, any lint or gum adhering to the saws will be scraped there from. It is to be understood of course that the number of blades can be increased or diminished to suit the number of saws constituting the gang to be cleaned and, moreover, the blades and the fingers can be made of different lengths so as to adapt the attachment to saws of different diameters.

By providing the curved fingers 8 which engage the spacing rings C, the blades are prevented from springing downwardly when subjected to excessive pressure by the material adhering to the saws and, moreover, lateral displacement of the blades and possible injury to the saws is thus avoided.

What is claimed is A saw cleaning attachment for cotton gins, including resilient knives arranged in pairs, said knives having parallel working edges and the knives of each pair converging upwardly toward the knives of the neXt adjoining pairs, there being a free open space between the knives of each pair for the escape In testimony that I claim the foregoing therethrongh of material removed from the as my oWn, I have hereto aflixed my signasaws, means connecting the knives at one ture in the presence of two Witnesses.
